A custom wheel may seem simple, yet the production process that stands behind it is by no means an easy thing to do. Manufacturing of a rim starts by melting the material (magnesium or aluminum alloys, or steel) at an extremely high temperature. The raw material is poured in a pre-formed cast. The designers let the metal cool down, and then they trim off any excess material. After the sample is shaped, it is inspected for the imperfections and defects to guarantee the highest quality of the final product. In case there are any flaws, they are either cured at this stage or the wheel is modified altogether. Surely, rims are not made in the same way, so when a new design is created from scratch, each manufacturer may use a variation of the above process.
To make a custom wheel stronger, the ready product is brought into an oven to be heat-treated. After a rim is cooled, it is inspected once again. This time, the sample is examined for leaks and impact reaction. If a prototype complies with all the quality standards and requirements, and features a perfect fit for a certain vehicle, the ready sample is kept for future forgings and casts. The wheels that are made for distribution simply copy the technique used for the prototype. After the ready custom wheels are sprayed with primer, they are carefully scanned for any blemishes or shortcomings. At the end of the manufacturing process, the final finish is applied to the rims. Whatever finish you choose, be it chrome-plating, black-powder coating, or custom color, it is applied at this point.
